10 p, 1.4 MB Metal utilization in genome-reduced bacteria : Do human mycoplasmas rely on iron? / Peralvarez-Marin, Alex (Universitat Autònoma de Barcelona. Departament de Bioquímica i de Biologia Molecular) ; Baranowski, Eric (Université de Toulouse. Interactions Hôtes-Agents Pathogènes) ; Bierge, Paula (Universitat Autònoma de Barcelona. Institut de Biotecnologia i de Biomedicina "Vicent Villar Palasí") ; Quijada Pich, Oscar (Universitat Autònoma de Barcelona. Departament de Bioquímica i de Biologia Molecular) ; Lebrette, Hugo (Stockholm University. Department of Biochemistry and Biophysics) ; Universitat Autònoma de Barcelona. Institut de Neurociències
Mycoplasmas are parasitic bacteria with streamlined genomes and complex nutritional requirements. Although iron is vital for almost all organisms, its utilization by mycoplasmas is controversial. Despite its minimalist nature, mycoplasmas can survive and persist within the host, where iron availability is rigorously restricted through nutritional immunity. [...]

8 p, 490.7 KB Fumarate and nitrate reduction (FNR) dependent activation of the Escherichia coli anaerobic ribonucleotide reductase nrdDG promoter / Roca Subirà, Ignasi (Universitat Autònoma de Barcelona. Departament de Genètica i de Microbiologia) ; Ballana, Ester (Centre de Regulació Genòmica) ; Panosa Borràs, Anaïs (Universitat Autònoma de Barcelona. Departament de Genètica i de Microbiologia) ; Torrents Serra, Eduard (Institut de Bioenginyeria de Catalunya) ; Gibert, Isidre (Universitat Autònoma de Barcelona. Departament de Genètica i de Microbiologia)
The nrdDG promoter regulates transcriptional expression of the anaerobic ribonucleotide reductase of Escherichia coli, an essential enzyme required to supply the building blocks for DNA synthesis. In this work, binding of the pleiotropic FNR (fumarate and nitrate reduction) transcriptional regulator to the nrdDG promoter region and the effects of binding on transcription were investigated. [...]

8 p, 149.7 KB The active form of the R2F protein of class Ib ribonucleotide reductase from Corynebacterium ammoniagenes is a diferric protein / Huque, Yasmin (Stockholms universitet. Institutionen för Molekylär biovetenskap) ; Fieschi, Franck (Institut de Biologie Structurale. Laboratoire de Cristallographie Macromoléculaire) ; Torrents Serra, Eduard (Universitat Autònoma de Barcelona.

Institutionen för Medicinsk biokemi och biofysik) ; Sjöberg, Britt-Marie (Karolinska Institutet (Estocolm, Suècia). Institutionen för Medicinsk biokemi och biofysik)
Corynebacterium ammoniagenes contains a ribonucleotide reductase (RNR) of the class Ib type. The small subunit (R2F) of the enzyme has been proposed to contain a manganese center instead of the dinuclear iron center, which in other class I RNRs is adjacent to the essential tyrosyl radical. [...]

10 p, 348.8 KB The anaerobic (class III) ribonucleotide reductase from Lactococcus lactis. Catalytic properties and allosteric regulation of the pure enzyme system / Torrents Serra, Eduard (Universitat Autònoma de Barcelona. Departament de Genètica i de Microbiologia) ; Buist, Girbe (Rijksuniversiteit te Groningen. Department of Genetics) ; Liu, Aimin (Stockholms universitet. Institutionen för biofysik) ; Eliasson, Rolf (Karolinska Institutet (Estocolm, Suècia). Institutionen för biokemi) ; Kok, Jan (Rijksuniversiteit te Groningen. Department of Genetics) ; Gibert, Isidre (Universitat Autònoma de Barcelona. Departament de Genètica i de Microbiologia) ; Graslund, Astrid (Stockholms universitet. Institutionen för biofysik) ; Reichard, Peter (Karolinska Institutet (Estocolm, Suècia). Institutionen för biokemi)
Lactococcus lactis contains an operon with the genes (nrdD and nrdG) for a class III ribonucleotide reductase. Strict anaerobic growth depends on the activity of these genes. Both were sequenced, cloned, and overproduced in Escherichia coli. [...]

Institutionen för molekylärbiologi) ; Sjöberg, Britt-Marie (Stockholms universitet. Institutionen för molekylärbiologi)
Ribonucleotide reductases (RNRs) are key enzymes in living cells that provide the precursors of DNA synthesis. The three characterized classes of RNRs differ by their metal cofactor and their stable organic radical. [...]

20 p, 8.9 MB Methyl-hydroxylamine as an efficacious antibacterial agent that targets the ribonucleotide reductase enzyme / Julián Gómez, Esther (Universitat Autònoma de Barcelona. Departament de Genètica i de Microbiologia) ; Baelo, Aida (Institut de Bioenginyeria de Catalunya) ; Gavaldà, Joan (Hospital Universitari Vall d'Hebron) ; Torrents Serra, Eduard (Institut de Bioenginyeria de Catalunya)
The emergence of multidrug-resistant bacteria has encouraged vigorous efforts to develop antimicrobial agents with new mechanisms of action. Ribonucleotide reductase (RNR) is a key enzyme in DNA replication that acts by converting ribonucleotides into the corresponding deoxyribonucleotides, which are the building blocks of DNA replication and repair. [...]
